We describe a purely confidence-based geographic term disambiguation system that crucially relies on the notion of " positive " and " negative " context and methods for combining confidence-based disambiguation with measures of relevance to a user's query.
ver the next few decades, two emerging technologies—microfabrication and cellular engineering—will make it possible to assemble systems incorporating myriads of information-processing units at almost no cost, provided all units need not work correctly and that there is no need to manufacture precise geometrical arrangements among them. The shift to this… (More)
BACKGROUND L-type calcium channel (LTCC) and Na(+)/Ca(2+) exchanger (NCX) have been implicated in repolarization-dependent arrhythmias, but also modulate calcium and contractility. Although LTCC inhibition is negative inotropic, NCX inhibition has the opposite effect. Combined block may, therefore, offer an advantage for hemodynamics and antiarrhythmic… (More)
Due to the widespread impact of vitamin D on human health, the development of appropriate assays to detect deficiency of all vitamin D metabolites of pharmacological interest is being continuously improved. Although over 50 naturally-occurring metabolites of vitamin D are known to date, only very few are routinely detected in commercially available assays.… (More)
In recent years it has been recognized that vitamin D deficiency is associated with a wide range of diseases, including various types of cancers. Due to the enormous medical importance of vitamin D and its metabolites, their status in blood serum has to be accurately measured. Thus, the metabolites actually used as reference standards and also others of… (More)
The time-to-collision task is that of estimating the ratio of the distance of an object to the relative velocity in the direction of that object, based on time-varying images resulting from the 3-D motion of a camera with respect to the object. Traditional methods require large amounts of memory and computation time, and are not suited for real time… (More)
